RUNXIN F77B1 Automatic Filter

n

The RUNXIN F77B1 Automatic Filter controls water filtration with ease. In addition, it handles up to 18 000 L/h, making it perfect for medium to large filtration systems. Moreover, the valve allows you to program backwash cycles using a clear LED display. As a result, it reduces manual work and ensures consistent filtration.

n

Furthermore, the F77B1 supports 2″ connections and offers flexible installation, either top-mounted or side-mounted. For example, its ceramic sealing faces prevent leaks and corrosion. Therefore, this automatic filter works well with sand filters, carbon filters, and pre-RO setups, making it ideal for industrial and commercial water treatment applications.

Installation & Maintenance Tips

n

n
1. Ensure the valve is mounted on a compatible vessel (24″‑30″ tank diameter) with correct inlet/outlet sizing.

n

2. Connect power (AC100‑240 V) and set up according to time‑clock or meter‑type controls as required.

n

3. Program backwash sequence (service → backwash → fast rinse → service) based on application and media type.

n

4. Monitor the LED display for service indicators or outage warnings. Buttons lock after 1 minute of inactivity to prevent tampering.

n

5. Clean or replace media as required and ensure the valve recalibrates correctly after servicing.
